Edward Tian, a senior at Princeton University, has created an app to combat the misuse of ChatGPT, a powerful artificial intelligence tool. He has created an app that uses the previous AI system GPT-3, to detect text written by the AI system and help the public identify whether a machine has written something. He is concerned that while the technology is incredible, there are no safeguards to adopt it responsibly. The release of ChatGPT to the public has raised questions about the impact of AI on jobs, education and public discourse.
